如何重新启动结构组合器而不丢失现有数据?

我已经尝试过" carauction-network"在我当地的例子。但是,当我使用" startFabric.sh"启动网络时文件,它正在删除Couch DB&再次创建Couch DB,由于这些旧数据丢失了。请建议我们如何在不清除数据的情况下启动结构服务器。

fabric-dev-servers (以前称为fabric-tools)下的startFabric.sh不仅可以启动Fabric,还可以删除现有的Fabric容器并从Docker Images重新创建新容器。这样做的影响是您从Fabric中丢失了所有数据和业务网络。除了PeerAdmin @ hlfv1之外的所有商业网卡现在都没用了。

如果您想在创建Fabric后停止并启动它,请保留您的业务网络和数据,请遵循以下命令:

  • 切换到docker-compose.yml文件所在的目录(例如/home/<user>/fabric-tools/fabric-scripts/hlfv1/composer
  • 运行docker-compose stop以覆盖Fabric Containers
  • 运行docker-compose start以重新开始。

在使用docker-compose命令之前,必要位于正确的文件夹中。

VERSION UPDATE

使用Composer v0.20.x(适用于Fabric 1.2)文件夹&#39;名称/版本已更改:

/home/<user>/fabric-dev-servers/fabric-scripts/hlfv12/composer

使用Composer v0.19.x(旧版,适用于Fabric v1.1),文件夹名称/版本已更改:

/home/<user>/fabric-dev-servers/fabric-scripts/hlfv11/composer

在fabric-dev-server / fabric-scripts / hlfv11中编辑你的startFabric.sh,如下所示

要扩展R Thatcher的解决方案,如果您可以访问bash shell,则可以将此脚本放入fabric-dev-server文件夹中。它将按照上述步骤重新启动网络,而不会丢失数据。只需将cd插入正确的目录并运行docker-compose stop和docker-compose start。重新启动以恢复网络后,也可以正常运行。

#!/bin/bash
cd ./fabric-scripts/hlfv1/composer
docker-compose stop
docker-compose start

似乎微不足道,并没有增加太多讨论,但节省了时间。
